Having access to legal abortion can fundamentally shape women's lives and their relationship with the state. This paper examines how the liberalization of abortion laws affects women's institutional trust. We argue that abortion legalization represents both a tangible expansion of state-provided healthcare and a symbolic recognition of women's autonomy. The policy change operates through two mechanisms: first, by providing concrete improvements in women's reproductive freedom, health, and safety; and second, by signaling the state's commitment to universal rights and gender equality. Drawing on performance-based theories of political support, we hypothesize that legalization enhances institutional trust among women, with particularly strong effects among those of reproductive age and secular backgrounds. We leverage Mexico's recent subnational variation in abortion laws to test this argument, employing a difference-in-differences design that exploits the staggered timing of liberalization across states. Using LAPOP survey data, we compare trust levels between states before and after policy changes. This study contributes to our understanding of how reproductive rights policies shape state-society relations while providing novel evidence from a context where religious and cultural factors make abortion reform particularly contentious.
